Title: Method and device for processing tools using a laser beam
Inventor: HEINE PETER
IPC: B23K26/06
Filed: 1981-04-14
Abstract: An elliptically polarised laser beam is directed at the workpiece during processing of the latter by means of a laser beam which can be moved over the workpiece in the directions indicated by different coordinates, and particularly during the blanking of metal pieces, in order to achieve a high speed while also achieving a good cutting quality. In order to generate an elliptically polarised laser beam, a polariser is provided in the path of the laser beam and has at least one metallic mirror which is arranged in such a way that the plane of polarisation of the laser beam forms an angle (23) with the plane of reflection.

Title: Burner with a mixing chamber
Inventor: BRUEGGEMANN REINHOLD
IPC: F23D14/64
Filed: 1981-05-27
Abstract: In burners with mixing chambers, which have openings for automatic suction of combustion air, it can frequently happen that, according to the type of use, flame parts are sucked in too, which cause ignition inside the mixing chamber and consequently prevent development of the flame at the burner itself, the mixing chamber possibly being damaged in addition under the influence of the heating. The invention envisages suction of the combustion air along an annular channel which surrounds the nozzle inlet and in which the sucked-in combustion air assumes a very high flow speed. Furthermore, at the end of this channel, there is a diversion of the flow of the sucked-in combustion air. Both as a result of throttling the cross-section and the high flow speed asociated therewith and also of the length of the channel and finally the diversion at the end of the channel, any flame parts sucked in too are caused to undergo extinction so that undesirable ignition inside the mixing chamber cannot take place.

Title: Lorry with rollable loading bridge
Inventor: ALBERSINGER GEORG
IPC: B60P3/12
Filed: 1982-03-13
Abstract: Lorry for towing away and transporting passenger vehicles, with a hydraulically rollable loading bridge, by which means loading without the customary driving-up ramps is possible. The loading bridge is guided in the front region by means of rollers in the auxiliary frame and is lowered by means of a lever mechanism attached in the rear region of the lorry. About half of the lowering displacement is brought about by a lever rocker and the other half by a linear displacement by means of two independent hydraulic cylinders. The lorry superstructure can be equipped with a second loading bridge for receiving a further vehicle. The special characteristics of this second loading bridge are on the one hand the completely countersunk arrangement in the main loading bridge and the lever mechanism. The latter is composed of toggle levers, acted on by hydraulic cylinders, in the rear region and an unequal parallelogram in the front region, by which means a controlled movement of the second loading bridge into an advantageous forwardly inclined oblique position is brought about.

Title: Device for dispensing cotton wool balls
Inventor: LOOS FRED
IPC: A45D44/00
Filed: 1982-04-30
Abstract: The invention relates to a device for dispensing cotton wool balls, having a two-part receiving container for the cotton wool balls, the first part of which receiving container is provided with a passage opening which is partially closed by webs with an essentially circular cross section and by means of which the cotton wool balls are moved for the purpose of removal by means of a relative movement of the two parts of the receiving container. The relative movement of the two parts of the receiving container is achieved by gravity and the diameter of the webs corresponds essentially to the radius of the cotton wool balls (according to P 3135529). The object of the present invention consists in reducing the costs in a device of the type mentioned at the beginning by means of a simplified construction. This is achieved in that the first part of the receiving container is designed as an insert which is movable inside the second part relative thereto, the second part at least having guide surfaces for the first part and a passage opening for the cotton wool balls.

Title: Internally oxidised silver-tin alloy as a contact material, and process for producing it
Inventor: SHIBATA AKIRA
IPC: C22C32/00
Filed: 1982-05-21
Abstract: According to the invention, a fairly pronounced temperature increase of internally oxidised Ag-Sn alloy contact materials, resulting from the high contact resistance peculiar to these materials, is eliminated. The high contact resistance, which is caused by the high concentration of supersaturation of metal oxides, containing tin oxides, on the contact surface, is avoided by subliming, reducing or extracting the solution metals on the contact surface before the internal oxidation. The sublimation and other treatments can also be carried out after the materials have been subjected to the internal oxidation.

Title: Process and device for the optimisation of the heating curve of a heating plant
Inventor: HARRER HORST DIPL ING
IPC: G05D23/20
Filed: 1983-01-04
Abstract: Process for preferably fully automatic optimisation of the heating curve of a heating circuit. For the combination of the external temperature and the feed temperature of the heating system, a series of heating curves with at least two heating curves Yi = S . fi(x) having different curvature functions fi(x) is provided, the chords of which have identical gradients S. To optimise the heating curve, the room temperature is sensed and its deviations from the control reference value are determined and are evaluated in a predetermined manner as to whether they are tolerable or not. In the latter case, there is established either a new heating curve of the series of heating curves, with another curvature function, or a new heating curve derived by alteration of the gradient S of the chord of the series of heating curves.

Title: Optoelectronic end-of-tape deactivating circuit
Inventor: SCHUELEIN REINHARD DIPL ING
IPC: G11B15/08
Filed: 1983-03-19
Abstract: The invention relates to an optoelectronic end-of-tape deactivating circuit for a video, audio or data recording and/or reproducing apparatus. Due to differences in reflection of the automatic stop foils and of the tape of the recording media used in these apparatuses, as well as due to tolerances of the optical components used, an adjustment of the said circuit arrangement is necessary. According to the invention, this adjustment is performed automatically by a microcomputer and continuously monitored. In the case of such a controlled end-of-tape deactivating circuit, on the one hand a clear distinction between the recording medium and the automatic stop foils attached at the ends of the tape is possible and on the other hand a reliable response of the end deactivation when the automatic stop foils run into the scanning area of the optical circuit arrangement is ensured.

Title: Stencil slide
Inventor: PAGALIES HANS-GUENTHER
IPC: B43L13/20
Filed: 1983-04-08
Abstract: A stencil slide consists essentially of a frame (1), a slide (3) which is transversely displaceable within the frame and a stencil (4) which is guided to be displaceable leftwards in the slide. In order to improve the accuracy of register between frame and slide while retaining the necessary displaceability of the slide within the frame, so that the risk of tilting of the frame and slide can be largely avoided, at least one spring element is arranged, according to the invention, between or on the frame (1) and/or the slide (3) and may consist, for example, of a slit (9) and a projection (11), its spring action being oriented transversely to the sliding travel of the slide in the frame. As a result of the resilient spring action of this frictional connection, tolerances between frame and slide are made good and the necessary displaceability is retained. <IMAGE>
